OCPP Proxy for solar charges?

I have wallbox EV charger for my EV.
OCPP on the charger is used to re-imburse some of the charging cost to my employer.

But ideally i would use OCPP to control the charger (nexxtmove OCPP platform doesnt integrare enough with HA).

Is there some kind of OCPP proxy solution where I can control the charger from HA but still integrate with the OCPP platform for the recharging?
